"The need for a footing drain was a surprise to me during my basement remodel due to water leaking in through the blocks. Raman and his team got me on the schedule fairly quickly, did a great job. They also set up new plumbing for 2 bathrooms and a kitchen in the basement, and removed my old water heater and installed a tankless water heater. Any issues that came up, they were very quick to resolve (including an old copper pipe that they didn't install which welding came loose, and they were there same day to fix.) great honest service, reliable service. Pricing, well, plumbing is not cheap, but I think they are comparable to anyone in the business. I would definitely use them again. Thanks Drain Pro!"

"<p>.Job started 3 days late due to delays on a previous job.</p> <p>Crew arrived on time Monday, 6/29 and installed braces under the foundation on the front, north side of the house and front south side.  re-leveled foundation which had settled slightly over the years.  This was done manually. </p> <p>Crews also installed pop up drains and conduit to allow water to flow away from the house as it was accumulating in the crawl space, causing some issues.  This was done on all sides of the house and interconnected all of our downspouts. </p> <p>Finally, underneath the house, crews installed braces to better support interior walls and stabilize the floor, which was flexing somewhat.  While in code, it was annoying and this was taken care of as well as re-leveling the floor in the kitchen and dining areas.  They also installed fresh vapor barrier plastic in the entire crawlspace</p> <p>This work took one day longer than scheduled, however, despite some additional purchases, there was not additional cost to us.  I am very pleased with the work performed under extreme heat conditions.  I would use Matvey again.</p>"

"We had a tricky leak that needed tracking down. We could hear it, but not see it. Our usual plumber was not available, so found Schmitty's on AngiesList and called. Thankfully, he was available to come out that afternoon, and after some detective work we finally narrowed down the area. It was evening by then, so he brought Trace out first thing in the morning to dig under the foundation and expose the leak. Between the two of them, they solved the issue... which turned out to be not one, but four pinholes in the copper pipe underneath the cement slab foundation. Brian said it might be the trickiest soldering job on the least amount of available pipe (1/4") in a very tight area in 20 years. Their pricing was reasonable and fair for an emergency service. Would definitely call them again. Thanks Schmitty!"

"Went very well. The plumbing technician did a thorough job of checking our piping and also vleaned out a clogged drain. The electrical technician identified outlets that needed to be changed to meet code. Electrical work was very expensive though."

"Work was done quickly and professionally. Were very careful to collect and/or cleanup any water drips. Had to cut wall board in laundry room to repair hose bib. Removed as small a piece as possible and replaced when finished."

"We needed a new dishwasher, garbage disposal, drain kit and faucet installed. We also needed valves replaced We appreciated the customer service and technical expertise provided by Ellis and Ryan. They were very professional and thorough. Three stars for &#34;value for money&#34; only because it seemed very expensive. Maybe due to the addition of replacing some of our PVC lines and valves. But we chose a trusted company because we can&#39;t risk water damage."

"Had a great experience with WA Evergreen Insulation from start to end. Rob came to my house, quoted me an insulation install, made absolutely sure that they would not cover any existing knob and tube with insulation and prevent a fire. The crew showed up and completed the job in one day. Once they got started it was clear they knew exactly what they were doing - and they managed to shimmy into the extremely small attic access and cleaned up my rat jerky in the crawlspace! I'm very happy with this job and with this company!"

FAQs for sump pump or interior foundation drains installation projects in Black Diamond, WA

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
